The traditional school Otonokizaka High is situated between the three towns of Akihabara, Kanda, and Jimbocho. This school is also in imminent danger of closing. Because of this crisis, the second year student Honoka Kosaka takes center stage with eight others to do something about it! "To protect the school we love so much, we have to do all we can... We have to become school idols! By becoming idols and advertising how great our school is to the world, more students will want to apply!"
